There are some new features of CSR V3.1: 1) Consistent information model (ISO 19115) for all resource types (previously resources were called component or service). 2) Update the registration page and search page to ensure the same layout and content for all resources. 3) Add the support for mime type. Once any items in "Supportive Information Standards" were selected, CSR will find the corresponding MIME type from SB's xml document, and output the MIME type as keyword in ISO XML. 4) Removed all old "service" resources, and mapped them to one of the following resource types: "Analysis and Visualization", "Catalogues, Inventories and Metadata Collections", "Alerts, RSS, and Information Feeds". See SB email attachment (not included in these notes) for the mapping rule from existing service to new resource type.

(from 24-Sept-2013 OGC TC meeting)

DA: at OGC TC, 24 Sept 2013, OGC Naming Authority committee suggested solution for MIME type assignments for OGC web services, is to define a MIME type that identifies each standard web service getCapabilities syntax (eg, WMS, WFS, WCS, CSW, SOS). This will be much more actionable than something generic like "application/xml", and would not require compound MIME type content (xml for capabilities, something else for data payload, which would be identified anyway in capabilities doc)
